O presente trabalho visa analisar e verificar o respeito aos direitos fundamentais das crianças e dos adolescentes frente às novas ferramentas de exposição existentes na sociedade contemporânea. Assim, buscar-se-á ...

Abstract Coaxial aircells are designed and fabricated to measure the electromagnetic properties of ferrite materials in the frequency range from 1 MHz to 3.6 GHz. These S-parameters are actually measured connecting the a...

En este trabajo estudiamos desigualdades mixtas con pesos para operadores multilineales y (sub)multilineales. Vale el siguiente teorema: Sean w1,...,wm ∈ A1 y sea v ∈ A∞. Sea ν = w 1 m 1 ...w 1 m m . Entonces exis...

Dialysate sodium (Nα) and ultrafitration (UF) profiling are two methods to reduce dialysis-induced hypotension. The aim of this study was to determine the efficacy of combining these techniques to reduce dialysisinduced...

Objetivou-se avaliar os efeitos da redução da densidade energética da dieta sobre a qualidade de ovo de codornas japonesas, mantendo a mesma relação energia metabolizável (EM):nutrientes. Foram utilizadas 400 codor...

Abstract Objective To evaluate the effect of gradually increasing orthodontic force magnitude compared with a constant force magnitude on the rate of tooth movement during maxillary canine retraction. Methods This split-...

In this work by using sol-gel auto-combustion synthesis was synthesized single-phase magnesium-substituted lithium ferrite at different pH reaction medium. The synthesized materials were investigated by X-ray and Mossbau...

As a non-destructive and rapid technique, optical scatterometry has gained widespread use in the measurement of film thickness and optical constants. The recent advances in deep learning have presented new and powerful a...

In this investigation, the experimental FT-IR and FT-Raman spectra of cholesterol in the solid phase and in ethanol solution have been combined with the B3LYP/6–311++G** calculations and the scaled quantum mechanical f...

Durante casi tres siglos, la vida de la prensa se desarrolló en una constante situación monolocutiva, en la cual la palabra del público sólo se filtraba en minúsculos intersticios, como aquel proporcionado por el cl...

The choice of optimal electrolytes is crucial for improving the electrochemical performance of a lithium air battery because it determines the morphology of the discharge products in the cathode and the conductivity of t...

The article provides a comprehensive theoretical analysis of the phenomenon of compassion fatigue in nurses. The relevance of the topic is due to the increase in the emotional burden on medical personnel in the context o...

Homogenizationmodels are widely used to predict the evolution of texture (crystal preferred orientations) and resulting anisotropy of physical properties in metals, rocks, and ice. They fail, however, in predicting two m...

Power electronic devices are used to integrate clean energy systems (CES) like wind, solar, and other energy sources into the grid to meet the load demand. The parallel operated-inverters (POI) can improve the power capa...

Las concepciones arqueológicas tradicionales suelen considerar a los materiales como inertes y pasivos, capaces de obtener forma sólo mediante la acción de un agente humano. Nuevos enfoques llevan a repensar estos ví...

Nanostructure CaCu 2.90 Zn 0.10 Ti 4 O 12 (CCZTO) electronic ceramic was synthesized by semi-wet route. The objective of this route is to enable the calcination and sintering processes to go for completion in shorter tim...

La esterilización por calor es uno de los procesos más utilizados para extender el período de aptitud de alimentos y hacerlos más seguros para el consumo humano. Existe una amplia cantidad de trabajos sobre análisis...

Copper metal nanoparticles (Nps) have received increasing interest during the last years due to their potential applications in several fields of science and technology. Their optical properties depend on the characteris...

ABSTRACT In this study homo and hetero trinuclear complexes of cobalt (II), nickel (II) and copper (II) were prepared by the reaction of their salts (chloride and nitrate) with a Schiff base ligand derived from vanillin ...

The diazabicyclooctane (DBO) inhibitor avibactam (AVI) reversibly inactivates most serine β-lactamases, including the CTX-M β-lactamases. Currently, more than 230 unique CTX-M members distributed in five clusters with ...

Five substituted pyrochlore nanooxides such as Nd1.9Ho0.1Zr1.8Ce0.2O7, La1.95Ce0.05Zr0.29Ce1.71O7, Y1.79Pr0.21Ru1.99Pr0.01O7, Dy1.9Yb0.1Mn1.93Cu0.07O7 and Dy1.99Sr0.01Sn2O7 were synthesized by coprecipitation method. The...

In this research, we investigate the mechanical, phonon dispersion, and electronic properties of Niobium (Nb) using Density Functional Theory (DFT). Utilizing the Quantum ESPRESSO package, we performed comprehensive DFT ...

The coal permeability is the key parameter for the gas seepage characteristics and the migration law, and the structural anisotropy of the coal seam makes the permeability have obvious orientation dependence. By assumein...

In recent years, sporting events have evolved into complex experiences that extend well beyond the competition itself, bringing together entertainment, community interaction, and brand engagement. In this context, unde...
